This product is obsolete/discontinued and no further stocks are available. Please see alternatives in the category links above.

Ability Level 3: IntermediatePre-Assembled and Kit versions available

This extremely sensitive ultrasonic motion detector circuit uses a quartz crystal to lock the detector frequency for maximum stability and reliability. The circuit can be set to pick up the slightest air movement (wind blowing, hot air rising).

All components, including the crystal controlled oscillator, detector circuits and a pair of edge mounted ultrasonic transducers, are mounted on a single board. Only the power supply and Signal Out connection wires are required.

  • Detection range of up to about 3-4 metres
  • Adjustable sensitivity
  • Red LED active indicator
  • 8.5V signal output - capable of driving an external relay (e.g. Order Code 1168) or other low power circuit
  • Designed for indoor use
  • Not recommended for battery operation*

* Although a PP3 battery clip is included we have found the circuit operates best with a 12Vdc regulated mains adapter.
